A patient presents to the emergency department with a high fever, chills, chest pain worsened by deep breathing, and a cough producing rusty-colored sputum. Which of the following diagnostic tests is most likely to confirm the nurse's suspicion of pneumonia?
Pulmonary Function Test (PFT)
Electrocardiogram (ECG)
Complete Blood Count (CBC)
Chest X-ray
The Correct Answer is D
A. Pulmonary Function Test (PFT). PFTs assess lung function but do not provide diagnostic information for infections like pneumonia.
B. Electrocardiogram (ECG). An ECG assesses heart function and would not help in diagnosing a respiratory infection like pneumonia.
C. Complete Blood Count (CBC). A CBC may indicate infection through elevated white blood cells, but it does not confirm pneumonia or identify its location in the lungs.
D. Chest X-ray. A chest X-ray is the most useful diagnostic tool to confirm pneumonia. It can reveal infiltrates or consolidation in the lungs, which are characteristic of pneumonia.

Correct Answer is D
Explanation
A. Include high-fat foods to maintain weight. High-fat foods can worsen symptoms in ulcerative colitis by increasing bowel irritation and causing malabsorption. A balanced diet that is low in fat is usually recommended.
B. Eat three large meals a day to ensure adequate nutrition. Large meals can increase digestive workload and exacerbate symptoms. Smaller, more frequent meals are generally better tolerated.
C. Increase intake of dairy products to boost calcium levels. Many patients with ulcerative colitis are lactose intolerant or sensitive to dairy, which can worsen symptoms. Calcium can be obtained from other sources if needed.
D. Consume a low-fiber diet to minimize bowel irritation. A low-fiber diet can reduce mechanical irritation in the bowel, which is beneficial during flare-ups of ulcerative colitis.
Correct Answer is D
Explanation
A. Mild wheezing: Mild wheezing can be a common symptom in COPD and does not immediately indicate a severe complication unless it worsens suddenly.
B. Fatigue and general malaise: Fatigue and malaise are often chronic in COPD and do not necessarily indicate an acute complication.
C. Increased sputum production: While increased sputum could suggest an infection, it is not the most urgent sign of a severe complication.
D. Sudden onset chest pain and dyspnea: Sudden chest pain and dyspnea are concerning for a pneumothorax or pulmonary embolism, both of which are potential complications in COPD and require immediate attention.
